[0037] The reward control unit 30F consumes the rewards held by the user. When the reward consumption condition is satisfied, the reward control unit 30F consumes the rewards held by the user. The reward consumption condition is included in the reward update condition.

[0038] In particular, when the reward control unit 30F purchases a product through an e-commerce service, it consumes the rewards held by the user according to the instruction from the user. When the reward control unit 30F contracts for a trip through a travel service, it consumes the rewards held by the user according to the instruction from the user.

[0039] <Reward management database 31A> As shown in FIG. 4, the storage unit 31 stores a reward management database 31A. In the reward management database 31A, a reward ID, date and time information, a user ID, a service type, a reward type, and a reward value are associated with each other.

[0040] The reward ID is information that can identify the update of the reward corresponding to the user ID. The date and time information is information indicating the date and time when the update of the reward corresponding to the user ID was performed. The user ID is information indicating the user for whom the update of the reward was performed. The service type is information indicating the service that caused the update of the reward corresponding to the user ID. The reward type is information indicating the type of the reward for which the update was performed. The reward type includes, for example, a regular reward and a time-limited reward. The reward value is the reward value for which the update of the reward corresponding to the user ID was performed. The reward value can identify whether a reward was granted corresponding to the user ID or whether the reward corresponding to the user ID was consumed.

[0041] In this way, when updating the reward corresponding to the user ID, information regarding the reward is registered in the reward management database 31A. Thereby, based on the reward management database 31A, information regarding the update of the reward corresponding to the user becomes identifiable.

[0042] <User management database 31B> As shown in FIG. 5, the storage unit 31 stores the user management database 31B. In the user management database 31B, a user ID, a usage rank, a total held reward value, a normal held reward value, and a limited-period held reward value are associated with each other. In the user management database 31B, a user ID and a plurality of service types are associated with each other. In the user management database 31B, a plurality of update types are associated with the service type. The update types include a total reward value, a normal reward value, and a limited-period reward value. In the user management database 31B, a user ID, a plurality of service types, and a user's behavior history are associated with each other. The user's behavior history may include impressions, click-through rates, and conversions. Note that in the user management database 31B, a password, a user address, and a user contact are associated with the user ID.

[0043] The total held reward value is information indicating the total of the reward values currently held by the user. The normal held reward value is information indicating the total of the normal reward values currently held by the user. The limited-period held reward value is information indicating the total of the limited-period reward values currently held by the user.

[0044] The service type is information indicating the service that causes the update of the reward corresponding to the user ID. The service type may include all services, a first service, and a second service. All services is information indicating all services. The first service may be, for example, an e-commerce service. The second service may be, for example, a travel service.

[0045] The update type is information indicating the type of reward update corresponding to the user ID. The update type may include grant and consumption. Grant is information indicating the grant of a reward to the user. Consumption is information indicating the consumption of the reward held by the user.

[0046] The total reward value is information indicating the total of the reward values corresponding to the user ID, service type, and update type. The normal reward value is information indicating the total of the normal reward values corresponding to the user ID, service type, and update type. The limited-time reward value is information indicating the total of the limited-time reward values.

[0047] The total reward value, normal reward value, and limited-time reward value corresponding to the user ID, service type, and update type are reward values within a predetermined reference period, but may also be reward values regardless of whether they are within the reference period. The reference period may be, for example, one year, six months, or three months.

[0048] In this way, according to the update trigger of the reward corresponding to the user ID, the user management database 31B is updated. Thereby, based on the user management database 31B, the usage status of the user in a plurality of services can be identified.

[0049] <Winning probability table 31C> As shown in FIG. 6, the storage unit 31 stores the winning probability table 31C. The winning probability table 31C is a table for obtaining the winning probability. In the winning probability table 31C, the usage status and the winning probability are associated. The usage status includes the usage rank, the total held reward value, the consumed normal reward value caused by the first service, and the granted limited-time reward value caused by the second service. The winning probability includes the winning probability corresponding to the first prize and the winning probability corresponding to the second prize. In this way, by referring to the winning probability table 31C, the winning probability is obtained according to the usage status of the user in a plurality of services.

[0050] For a specific example, when the user's usage rank is high, the winning probability may be higher than when the user's usage rank is low. When the total reward value held by the user is high, the winning probability may be higher than when the total reward value held by the user is low. When the normal reward value given to the user due to the first service is high, the winning probability may be higher than when the normal reward value given to the user due to the first service is low. When the limited-time reward value consumed by the user due to the second service is high, the winning probability may be higher than when the limited-time reward value consumed by the user due to the second service is low.

[0051] The user's usage rank, the total reward value held by the user, the normal reward value given to the user due to the first service, and the limited-time reward value consumed by the user due to the second service are information proportional to the degree of user usage. Thus, the user's usage rank, the total reward value held by the user, the normal reward value given to the user due to the first service, and the limited-time reward value consumed by the user due to the second service are information indicating the degree of user usage. Thus, when the second usage situation is a usage situation with a lower degree of usage than the first usage situation, when the user's usage situation is the first usage situation, the winning probability may be higher than when the user's usage situation is the second usage situation.

[0052] <User Information Management Process> Here, the user information management process will be described with reference to FIG. 7. The user information management process is a process executed by the control unit 30 at every predetermined cycle. In the following processes, it is described on the premise that the user authentication has been performed normally.

[0053] As shown in FIG. 7, in step S10, the control unit 30 determines whether the action history update condition is satisfied. The action history update condition is satisfied when the action history of the user in a plurality of services is generated. In this case, the control unit 30 may determine whether the action history update condition is satisfied based on whether it has received the action history of the user from the server that provides the service.

[0054] When the control unit 30 determines that the action history update condition is not satisfied, the process proceeds to step S13. When the control unit 30 determines that the action history update condition is satisfied, the process proceeds to step S11.

[0055] In step S11, the control unit 30 executes an action history acquisition process. In the action history acquisition process, the control unit 30 acquires the user's action history by communicating with the server that provides the service. The user's action history may include a user ID, a service type, and an action type.

[0056] In step S12, the control unit 30 executes an action history update process. In the action history update process, the control unit 30 updates the user management database 31B so as to change the action history corresponding to the user ID based on the user's action history acquired in step S18. In this way, the control unit 30 registers the user's action history.

[0057] In step S13, the control unit 30 determines whether the reward update condition is satisfied. The reward update condition is satisfied when the reward value corresponding to the user is updated. Specifically, the reward update condition is satisfied when a reward is given to the user in a plurality of services. The reward update condition is satisfied when the reward corresponding to the user is consumed in a plurality of services. The control unit 30 may determine whether the reward update condition is satisfied by communicating with the server that provides the service.

[0058] When the control unit 30 determines that the reward update condition is not satisfied, the process proceeds to step S17. When the control unit 30 determines that the reward update condition is satisfied, the process proceeds to step S14.

[0059] In step S14, the control unit 30 executes reward information acquisition processing. In the reward information acquisition processing, the control unit 30 acquires reward information by communicating with a server that provides a service. The reward information may include a user ID, a service type, a reward type, a reward update type, and a reward value to be updated.

[0060] In step S15, the control unit 30 executes reward information registration processing. In the reward information registration processing, the control unit 30 registers the reward information acquired in step S11 in the reward management database 31A.

[0061] Taking a specific example, in step S14, the control unit 30 acquires a user ID, that a reward is to be given to the user, the reward value to be given, and the reward type from the e-commerce server 12. In this case, in step S15, the control unit 30 registers the user ID, the service type, the reward type, and the reward value to be given in the reward management database 31A. In particular, the control unit 30 registers the e-commerce service as the service type in the reward management database 31A.

[0062] In step S14, the control unit 30 acquires a user ID, that a reward corresponding to the user is to be consumed, the reward value to be consumed, and the reward type from the travel management server 13. In this case, in step S15, the control unit 30 registers the user ID, the service type, the reward type, and the reward value to be consumed in the reward management database 31A. In particular, the control unit 30 registers the travel service as the service type in the reward management database 31A.

[0063] In step S16, the control unit 30 executes reward value update processing. In the reward value update processing, the control unit 30 updates the user management database 31B so as to change the reward value corresponding to the user ID based on the reward information registered in the reward management database 31A. In particular, the control unit 30 updates the total held reward value, the normal held reward value, and the period-limited held reward value corresponding to the user ID in the user management database 31B. Also, the control unit 30 updates the total reward value, the normal reward value, and the period-limited reward value corresponding to the user ID, service type, and update type in the user management database 31B. In this way, the control unit 30 registers information regarding the reward value corresponding to the user.

[0064] In step S17, the control unit 30 determines whether the usage rank update condition is satisfied. The usage rank update condition is satisfied when the usage rank corresponding to the user is updated. Specifically, the usage rank update condition may be satisfied when the user starts using a plurality of services. In this case, the control unit 30 may determine whether the usage rank update condition is satisfied based on the service type for which the user's usage has started by determining whether it has received information indicating that the user's usage has started from the server that provides the service.

[0065] The usage rank update condition may be satisfied when the usage amount used by the user in a plurality of services exceeds a predetermined amount. In this case, when the control unit 30 receives information regarding the usage amount used by the user from the server that provides the service, the control unit 30 may determine whether the usage rank update condition is satisfied based on whether the usage amount used by the user exceeds the predetermined amount.

[0066] If the control unit 30 determines that the usage rank update condition is not satisfied, it ends the user information management processing. If the control unit 30 determines that the usage rank update condition is satisfied, it proceeds to step S18.

[0067] In step S18, the control unit 30 executes a usage rank acquisition process. In the usage rank acquisition process, the control unit 30 acquires usage rank information. The usage rank information may include a user ID and a usage rank. In particular, the control unit 30 may acquire usage rank information including the usage rank corresponding to the user ID based on the result determined in step S17.

[0068] In step S19, the control unit 30 executes a usage rank update process. In the usage rank update process, the control unit 30 updates the user management database 31B so as to change the usage rank corresponding to the user ID based on the usage rank information acquired in step S18. In this way, the control unit 30 registers information regarding the usage rank corresponding to the user. In particular, the control unit 30 registers information regarding the usage rank of the user based on the usage status of the user in a plurality of services.

[0069] <Lottery control process> Next, the lottery control process will be described with reference to FIG. 8. The lottery control process is a process executed by the control unit 30 at a predetermined cycle.

[0070] In step S20, the control unit 30 determines whether there is a lottery instruction by the user through communication with the terminal device 18. The lottery instruction is an instruction given by the user after accessing a predetermined site, but it may also be the act of accessing the predetermined site itself. That is, the lottery instruction may be given by the user at the predetermined site. In this way, the control unit 30 determines whether there is a lottery instruction by the user based on whether it has received the user's lottery instruction at the predetermined site.

[0071] When the control unit 30 determines that there is no lottery instruction by the user, it ends the lottery control process. When the control unit 30 determines that there is a lottery instruction by the user, it proceeds to step S21.

[0072] In step S21, the control unit 30 executes a usage status acquisition process. In the usage status acquisition process, the control unit 30 acquires the usage status of the user in multiple services. In particular, the control unit 30 acquires the usage status of the user in multiple services by referring to the user management database 31B.

[0073] In detail, the control unit 30 acquires information regarding rewards granted to the user in multiple services as the user's usage status. The control unit 30 acquires information regarding rewards consumed by the user in multiple services as the user's usage status. The control unit 30 acquires reward value held by the user as the user's usage status. In addition, the control unit 30 acquires at least one of a normal reward value and a time-limited reward value among the reward values ​​held by the user as the user's usage status. The control unit 30 acquires information regarding the user's usage rank as the user's usage status.

[0074] In step S22, the control unit 30 executes a winning probability acquisition process. In the winning probability acquisition process, the control unit 30 acquires a winning probability corresponding to the user's usage status in response to a user's instruction on a specific site. In particular, the control unit 30 acquires a winning probability corresponding to a winning grade. In this way, the control unit 30 acquires a winning probability corresponding to the user's usage status upon receiving a lottery instruction from the user.

[0075] As a specific example, the control unit 30 may obtain a higher winning probability when the user's usage rank is high than when the user's usage rank is low. The control unit 30 may obtain a higher winning probability when the user's total held reward value is high than when the user's total held reward value is low. The control unit 30 may obtain a higher winning probability when the user's granted normal reward value resulting from the first service is high than when the user's granted normal reward value resulting from the first service is low. The control unit 30 may obtain a higher winning probability when the user's consumption period limited reward value resulting from the second service is high than when the user's consumption period limited reward value resulting from the second service is low.

[0076] Thus, when the second usage situation has a lower degree of utilization than the first usage situation, the control unit 30 obtains a higher winning probability when the user's usage situation is the first usage situation than when the user's usage situation is the second usage situation.

[0077] In step S23, the control unit 30 executes an advertisement providing process. In the advertisement providing process, the control unit 30 transmits the advertisement stored in the storage unit 31 to the terminal device 18 for which a lottery instruction has been given. In this way, the control unit 30 provides the advertisement submitted by the advertisement provider according to the user's instruction.

[0078] In step S24, the control unit 30 determines whether or not the lottery condition is satisfied. The lottery condition may be satisfied when the viewing of the advertisement is completed before a predetermined time elapses. In this case, when the control unit 30 determines, through communication with the terminal device 18, that the viewing of the advertisement has been completed before the predetermined time elapses, the control unit 30 determines that the lottery condition is satisfied. When the control unit 30 determines that the lottery condition is not satisfied, the lottery control process ends.

Therefore, while diversifying the services used by the user, it is possible to enhance the user's awareness of the usage rank in multiple services, and to raise the expectation of participating in the lottery.

[0090] (1-8) When the usage status is the first usage status, the control unit 30 acquires a higher winning probability than when the usage status is the second usage status with a lower degree of usage than the first usage status. For this reason, by increasing the degree of usage of the user in multiple services, the winning probability of the lottery can be increased. Therefore, while diversifying the services used by the user, it is possible to enhance the user's awareness of the usage status in multiple services, and to raise the expectation of participating in the lottery.

[0091] In particular, users with a higher reward value they possess tend to be more likely to consume the reward value they possess than users with a lower reward value. Thus, when a user has a high reward value, by conducting a lottery based on a higher winning probability than when the user has a low reward value, it is possible to increase the likelihood that the user will consume the reward value in a plurality of services.

[0092] (1-9) The control unit 30 conducts a lottery with a winning probability corresponding to the winning rank. Therefore, it is possible to provide the user with a lottery opportunity according to the winning rank.
